CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your H3 Hummer running at its best, a CSF Heavy-Duty/High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on and off road, a heavy-duty performance radiator is a must-have for off-roaders, overlanders, and adventurers. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.The CSF H3 Hummer radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Whether you are off-roading, towing, or just casually driving, trust the cooling experts at CSF for the best performing, highest-quality, and most reliable radiators.

Our Go-To Pull-Ups for Potty Training
Size: 2T-3T, Unit Count: 124
We’ve tried a few different brands during potty training, and we always come back to Pull-Ups. They fit my daughter really well, are easy for her to pull up and down on her own, and hold up great overnight without leaking. The sides tear easily for quick changes, which is super helpful when you’re out and about. The designs are also cute and helped make potty training a little more exciting for my toddler. Definitely a staple in our house during this stage!

Luvs pulls up are the best
Size: 5T-6T, Unit Count: 48
I love this brand. It’s very secure, and the adjustable band makes it easy to tighten without taking off my child’s pants. It doesn’t leave an odor, the texture is smooth, and my child is always comfortable. The price matches the quality, and there’s no leakage or spillover. Overall, it’s very durable. Make sure to have it correctly fastened because the Velcro can leave scratches on child skin.

Fits true to size and easy to pull up and down by my toddler. Very absorbent - perhaps a little too absorbent as it's taking my daughter forever to be potty trained and she's content in her soiled training pants... Great quality overall.

They prevent leaks, and fit great!
We have always used Huggies diapers for our babies and young toddlers because they were the only ones that never leaked or caused a rash. My second daughter was fully potty trained at 2.5 years old and never needed pull-ups. However, our third daughter, who also trained at 2.5 years old, digressed with her nighttime potty training due to instability - we moved twice within the first 6 weeks after she potty trained. So we had to get pull-ups for her to wear at night. Obviously since we loved Huggies diapers, we tried Huggies Pull-Ups, and again, they did not disappoint! They never leak, even on nights when she doesn't get up to go at all, and has lots of pee, and they have never caused a rash either, no matter how full. She's been using them for 1.5 years, at night, and we have never had any issues. They are dependable: decently comfortable to the child, do not cause rashes, fit properly with the ability to adjust at the thigh (if needed), and they prevent leaks! I highly recommend them!
